The atomic number of a cation does not change during the formation of the ion. It remains the same as the atomic number of the neutral atom from which the cation is formed. The atomic number is the number of protons in an atom's nucleus, and this number defines the chemical element. In the formation of a cation, an atom loses one or more electrons but the number of protons (and thus the atomic number) remains unchanged.
